Clinical depression (also called major depressive disorder, or sometimes unipolar when compared with bipolar disorder or sometimes called manic depression]) is a state of intense sadness, melancholia or despair that has advanced to the point of being disruptive to an individual's social functioning and/or activities of daily living. Although a low mood or state of dejection that does not affect functioning is often colloquially referred to as depression, clinical depression is a clinical diagnosis and may be different from the everyday meaning of "being depressed." Many people identify the feeling of being depressed as "feeling sad for no reason", or "having no motivation to do anything." One suffering from depression may feel tired, sad, irritable, lazy, unmotivated, and apathetic. Clinical depression is generally acknowledged to be more serious than normal depressed feelings. It often leads to constant negative thinking and sometimes substance abuse.

Bipolar disorder, often referred to as manic-depression in the general literature, is a psychiatric condition defined by periods of extreme mood. These moods can occur on a spectrum ranging from debilitating depression to unbridled mania. Individuals suffering a bipolar disorder generally experience fluid states of mania, hypomania or what is referred to as a mixed states in concert with clinical depression. These clinical states typically alternate with a normal range of mood, which is termed euthymia. Bipolar disorder can range in severity from a mild annoyance to a serious lifelong disability.

There are many variations of this disorder. A person with bipolar disorder generally tends to experience more extreme states of mood than other people, even within the context of what might be considered "normal". Moods can change quickly (many times a day) or last for months. In psychiatric terms, this is called fast cycling or slow cycling, respectively. Bipolar individuals tend to have very 'black and white' thinking, where everything in life is either a positive aspect or a negative. Mood patterns of this nature are associated with distress and disruption, and a relatively high risk of suicide. Bipolar disorder is also associated with a variety of cognitive deficits, in particular, difficulty in organizing and planning. The disorder may also skew the ability to judge others' emotion, and alter sense of awareness.[1]
